  • the handheld terminal comprises various input means or traversing means which can be operated independently of one another independently of one another and which are embodied, for example, as a 6D mouse or as jog keys.
  • traversing means By means of the touch screen it is possible to assign each of the traversing means its own reference coordinate system.

  • the safety input device has an emergency stop button, a consent button and a mode selector switch.
  • a disadvantage of this embodiment is that an operator for safe operation of the virtual buttons is always forced to look at the touch screen to avoid incorrect inputs. The same applies to adverse environmental conditions such as strong light or darkness, which would complicate the operation of the touch screen.
  • a method for operating an industrial robot by means of a graphical user interface with touch display having control unit comprising the method steps: displaying at least one representing a function or mode of operation of the industrial robot virtual control on the touch Display, selection of a desired function or mode by operating the at least one virtual control element by an operator, detecting the confirmation of the at least one virtual control element and sending a control function corresponding to the selected function or mode to a safety means of the robot control, evaluation of the control command, executing the selected Function or operating mode, if an acknowledgment button is correctly actuated or identification matches.

Abstract

L'invention concerne un procédé pour commander un robot industriel (12) au moyen d'un appareil de commande (10) présentant une interface utilisateur graphique (18) pourvue d'un écran tactile (20). Pour améliorer la sécurité de commande du robot industriel, au moins un élément de commande virtuel représentant une fonction du robot industriel (12) est affiché sur l'écran tactile, un signal de commande affecté à celui-ci est envoyé à une commande de sécurité et une image est produite au moyen de la commande de sécurité, l'image étant alors affichée sur l'écran tactile (20). En cas de contact avec l'image sur l'écran tactile, un envoi en retour vers la commande de sécurité est réalisé afin d'exécuter une fonction du robot industriel lorsqu'une correspondance est détectée entre l'image représentée et le contact avec l'image sur l'écran tactile.
